To the upper ends of the arms D' are pivoted cap-plates E', which are adapted to be swung from the said arms D' or closed over the upper ends thereof, and bolts F' are provided, by means of which the said cap-plates may be bolted to the arms D', as shown in Fig. l.

G represents a shaft which is j ournaled in bearings in the outer ends of arms C'. To the said shaft is secured a pair of sprocketwheels H', and to one end of said shaft is secured a spur-wheel l'.

K' represents a pair of endless sprocketchains, which engage the wheels H', NV, Y, and Z. The said sprocket-chains are connected together at suitable intervals by transverse flights L', and said chains and iiights constitute an endless carrier.

M' represents a rock-shaft, which is journaled in a pair of bearings N', that project from the outer end of the trough A. To the said rock-shaft is attached a lever O', which is provided with a locking-bolt P', that is adapted to engage a toothed sector R' and thereby secure the lever at any desired position. The said lever is connected to the pivoted arms or standards S by means of a pair of link-rods S', and thereby the latter may be turned to any desired inclination by operating the lever O', and consequently cause the wheels W to tighten or loosen the endless sprocket-chains according to the angle at which trough L is arranged.

The stops U are adapted to come in contact with the upper edges of the vert-ical extensions or wallsE when the arms or standards S are turned to nearly a horizontal position, as shown in Fig. 2.

a represents the corn shelling machine, which is of the form now in common use, is provided on its front side with the lower hopper b, and has an inclined endless elevator c and an upper hopper d at the upper end of the elevator, whereby the corn will be carried from the lower hopper and dropped into the upper hopper.

The said shaft is pro' e represents the driving-shaft of the cornsheller, and f represents a sprocket-wheel, which is attached to the said shaft.

T' represents a pair of inclined beams, which are adapted to be secured to opposite sides of the case or frame of the corn-Sheller, and which project from the upper front cor ner thereof.

U represents a frame, which comprises a pair of vertical arms V', the cross-bar WV', which connects the lower ends of the said arms, and a cross-bar X', which connects the said arms and is arranged a suitable distance above the bar W. The arms V' are pivoted at a suitable distance from their upper ends, between the outer ends of the inclined beams T', by means of bolts Y', and thereby the frame U is adapted to swing in a vertical plane. To the under side of the bar W', at the center thereof, is secured a circular plate or ring Z'.

A2 represents a vertical shaft which is jou rnaled in central bearings in the bars WV' and X', and has a miter-wheel B2 at its upper end and a similar wheel C2 at its lower end. Swiveled to the said shaft is a beam or plate D2, which bears against the lower side of the ring or plate Z' and is adapted to swing or turn in a path at right angles to that of the frame U. From the ends of the said beam orplate D2 depend a pair of hangers E2, having bearings at their 'lower/ends, in which is journaled a shaft F2. The said shaft has a wheel G2, which engages the miter-wheel G2, and to one end of the said shaft is keyed a spur-wheel H2.

IOO

I2 represents a shaft which is journaled in bearings in the upper ends of arms V'. To this shaft is secured a wheel K2, which meshes with the wheel B2, and to one end of thessaid shaft is secured a sprocket-wheel L2, which is connected to the wheel f by means of an endless sprocket-chain M2, and thereby the motion of the drivinmshaft e of the cornshelling machine is communicated to the shaft I2, from the latter to the shaft A2 by the gears B2 and K2, and from the shaft A2 to the shaft F2 by the gears C2 and G2.

The corn-shelling machine is arranged at a suitable distance from the corn-crib g, which is of the usual construction, and the shaft F2 is engaged in bearings formed between the upper ends of the standards or arms D and the cap-plates or arms E', and thereby the upper end of the inclined trough L and the conveyer are hinged to the said shaft and connected to the pivoted beam D2. Consequently the said conveyer may be extended from the cornshelling machine in any desired direction and disposed so that its trough A will lie alongside of the corn-crib. The upper end of the inclined trough L is above' the lower hopper b of -the corn-Sheller.

N2 represents a stop-board or fender, which is provided near its ends with a pair of depending standards O2, which are adapted to engage keepers P2, that are on opposite sides of the horizontal trough A, and thereby the IOS IIO

said stop-board or fender may be secured to either side of the said trough. Said stop board or fender Will be arranged on the side of the trough which is farthest from the corncrib, and when the corn-shelling machine is set in motion the endless carrier will be caused to travel in the direction indicated by the arrow in Figs. 1 and 2, so that the flights on the lower side of the said carrier will move upward and outward on the bottoms of the troughs and nearly or quite in contact therewith. The ear-corn is discharged in suitable quantities from the crib into the trough A either by tearing out the slats or boards on the side of the crib which is above the trough rig. s.

From the foregoing description it Will be understood that the corn has to be handled only once between the corn-crib and the Wagons While undergoing the process of being shelled.

Having thus described our invention, We claiml. The combination of the trough A, the Wheels Y at the outer ends thereof, the wheels Z, journaled at the inner end of said trough, the trough L, hinged to the inner end of trough A, the wheels H at the outer end of trough L, the pivoted standards S near the outer end of trough A, the AWheels W, having their bearings in the said standards, the endless carrier connecting the Wheels Y, Z, H, and XV, and the lever connected to the standard S, whereby the latter may be inclined to any desired position to tighten or loosen the endless carrier, and thereby adjust the latter to suit the inclination of the trough L, substantially as described.
